The Marin Trail

We stayed the Friday night in Llandudno, meaning it was only a short drive down the A470 to get to Llanrwst and the Marin trail starting point. There's a decent sized gravel car park at the start, or alternatively you can drive on further up the trail and park at a smaller car park near Hafna Mill.

The Trail is a loop so it really doesn't matter where you are starting from. There is also a huge network of fire roads all over these forest hills, so if you felt like it you could deviate from the Trail and explore a bit (don't try that without a map though).

In theory the trail is one way and the whole route is signposted with bright blue posts at vital points. Although the occasional one has been knocked over and the little arrows and a bit too little for my eyes.

This was the first ever bit of Mountain biking that both me and my old Raleigh have ever done and I wasn't sure what to expect really. The very first part of the trail, as you leave the car park is a bit like being thrown in the deep end and it certainly didn't do much for my confidence about completing the rest of the trail. Luckily this section is a bit of a one off and isnt very long. It's a single track, going slightly uphill with lots of loose slate stones, meaning it was an absolute bugger to get going without the rear wheel spinning out from under me. I'll put this mainly down to the total inexperience Raleigh feeling very awkward at first as it's the first time I've properly ridden it in a few years.

Once you're past this first bit it's time to start climbing (the bit I'm good at). All the climbs are on the open fire roads like this:
With a few exceptions they are all reasonably steep but easy inclines. Even so, it can be pretty knackering on some of the longer climbs when you are fighting the loose gravel and your knobbly tyres.

There are also plenty of footpaths dotted around these forests. Although it is well signposted at any points that you are likely to come across either walkers or vehicles.


The fast downhill single track sections should be exclusively bikes, but you never know, so it pays to keep an eye out ahead. I didn't take many photos of the single track downhill sections (because its too much fun to stop) but this photo is typical of how they weave through the trees with plenty of big lumps, bumps and rocks littering the route.

Not all the single tracks are hidden in the dense trees like this. Some take you through mossy damp woodland filled with freaky toadstools.....
or bridges over streams.....
This little bridge has had lumps built into it specially for making you crap your pants when you go flying over them to fast:
Further up the trail there is a fair sized lake, which with it's cystal clear water and shallow banks its very tempting for a quick dip on a hot day:


At the second smaller car park is the ruins of Hafna Mill - a lead ore processing mill.

Overall it was a great day out and took us around 4 hours to complete, but that was with quite a number of stops for breathers, running repairs & chocolate. Obviously I fell off quite a few times, but they are only ever slow sideways plonks where you meet a big rock too slowly and dont have the momentum to get over it.

You quickly get used to the idea that going that bit faster is actually safer. There is a sweet spot, depending on you bike and skill, where you are going fast enough to skip over the more uneven surfaces, but not so fast that you are sent into orbit on a lump or can't make a turn. If you are going too slow though, the bigger lumps will just chuck you off or you'll lose your balance at steeper slopes or rough turns.
I was expecting to see a plethora of megabucks bikes all day, but in reality there was a full range of bikes being used all the way from Turners to Raleighs like mine but with neither spds or a suspension fork fitted. These American guys pictured below had even gone down the uber safety route of full knee, shin and elbow pads - bit over the top if your ask me, but each to their own.

I finished the last couple of hundred yards on the route without a chain, as my split link gave up the ghost. Thankfully being so close to the end it was no big deal and not worth the time to fix. Once you are free wheeling it's suprising how much you can do without a chain. It was a nice little challenge to keep my momentum up, knowing that if I lost it there was no pedal power to get me going again.

In conclusion, you know it's been a good day when your legs have a tide mark:

Getting ready for the Marin Trail

A few things to do before we go to the Marin Trail

With my brothers help we did some bodging to my old Raleigh to get it ready for the first ever bit of actual mountain biking it's done in the 14 years since it rolled out of Nottingham.

To start with:

Swap the rear deraileur that doesnt fit properly.....
...for one that does...
The one that didnt fit properly was a replacement off ebay many years ago after the original disintegrated on the streets of Newcastle. It worked perfectly well for riding on the streets, but would have been a major liability on bumpy single tracks. While we were at it, I replaced the gear cable for a new one since shiny new cables tend to work better than rusty 14 year old ones.





Then the big job - swap the fork for the cheapo suspension fork I bought a few weeks ago.
Satisfyingly large spanner for the headset



















The bearings were in reasonable condition, but the bottom bearings were in desperate need of some new grease.

With the fork out, it got clamped in the vice....


...and the bottom bearing ring given some gentle persuasion to come off with a big pointy thing and a big hammery thing.

When that was off we found the bearing ring wouldnt fit onto the new fork. Being cheapo and chinese it hadnt been machined enough (you get what you pay for). After a bit of dremelling though it went on nice and tightly with a few knocks from a mallet.


The new fork had a shorter steerer than the original one. So we did away with the two original spacers to leave enough thread for the main nut to go back on.

With no compression on the fork you can see that the angle of the top tube has been raised by a couple of inches. I've no idea of this is good or bad - probably neither as the fork will compress with my weight over it as I go down the hills.


And finally a tiny bit of bodging to make the rear splattergaurd stay straight. These things are forever getting knocked to one side and are frankly a bit crap, but this should make it slightly less crap. One of many, many things that can be fixed with a hole and a ziptie.

Pump some air into the excessively knobbly Tioga Psycho II tyres and we are ready to go!

Transporting bits of bicycle by bike

The cheapo forks I ordered for my old MTB arrived. I'd had them delivered to my designated pick up point (parents house) so I had to go pick them up. It fitted quite easily on the Trek's rack, even if it did stick out a bit.

Not so long ago I would have nipped up in the car to pick up something like this, but since I was on my way home from work I just rode the 3 miles or so further and got them. It was also a good excuse to go down the section of Hyde Road that crosses the River Tame. It's always fun when the car drivers find they can't enter 'must past the cyclist' mode because I'm going faster than them.

Heres the forks in all their 'New Old Stock' glory.The MTB is purple so they should look suitably odd when fitted.
